BACKGROUND OF THE PRESENT INVENTION Field of Invention

The present invention relates to a height-adjustable jack and vertical modular component support for construction of beams and floor slabs in buildings, and more particularly to a u-shaped support that can be extended for a part of support posts in the temporary support system and a support system using the same

Description of Related Arts

During the construction of buildings, it is necessary to install a temporary support system consisting of a large number of support posts and horizontal ties on the ground, and place wooden or steel formwork on the temporary support to create the shape for the concrete to be poured in to form the beams and slabs. There are critical positions to place the support system below the formwork in order to support the beam and slab areas between adjacent beams. The bottom surface of the slab is located higher than the bottom surface of the load-bearing beam; and from a structural standpoint, two adjacent beams share the distributed load across the slab. Therefore, when the temporary support is provided for both beam and slab, the height of the support posts for supporting the beam is lower than that for supporting the slab. In order to set up this temporary support system, it is often necessary to prepare a higher combined temporary support for the slab, as it also bears the dispersed loading from the beam as well, which resorts to requiring more manpower and material resources, and as a result, increasing construction costs.

Once the fastening 102 are aligned with its respective fastening 401, the locking pin 5 is passed through the set of fastening through-holes 102 and 401 to secure the support post 1 and the connecting spigot 4 together. The support post 1 and connecting spigot 4 are both independently formed, and if either components are worn out, either can be replaced without discarding the entire height-adjustable jack and vertical modular component support, thereby saving overall cost.

According to embodiment, one end of the support post comprises of the external threaded section 101 and the opposite end of a circular unthreaded tube section 103, and a perforated connecting disc 6 is arranged on the external wall of the circular unthreaded tube section 103; the perforated connecting disc 6 is located above the U-shaped support base 2. The perforated connecting disc 6 is commonly used on support frames on conventional construction sites for efficiently connecting the support post 1 to various horizontal or inclined components. The perforated connecting disc 6 is also commonly used on various support systems on conventional construction sites for the same purpose.

In order to utilize the support post 1 itself as a connecting member, the fastening through-holes 102 are respectively provided at the end of the circular unthreaded tube section 103 and the end of the external threaded section 101; after the fastening through-holes 102 of the external threaded section 101 are aligned with one set of the fastening through-holes 401, the transverse locking pin 5 shall pass through the fastening through-holes 102 and 401 to join the support post 1 and the connecting spigot 4 together. The two fastening through-holes 102 are provided to facilitate the function of extension for the support post 1 at either ends.

The spindle nut 3 used as the height-adjusting component is integrally foiled by a rotating ring 301 with two support handles 302 symmetrically disposed on the external wall of the rotating ring 301; and the internal wall of the rotating ring 301 is threaded to correspond directly with the external threaded section 101 of the support post 1.

According to embodiment, only one transverse locking pin 5 is required, wherein the transverse locking pin 5 is a bolt; one end of the bolt is provided with a fixed nut, while the other end is provided with a detachable nut 7.
